【摘要】：閘門(mén)在水電廠正常運(yùn)行中起著非常重要的作用，不僅承擔(dān)著發(fā)電、防洪等任務(wù)，特別是汛期過(guò)程中，閘門(mén)系統(tǒng)的有效運(yùn)行是整個(gè)電廠防洪安全的保證，，同時(shí)也影響著整個(gè)電廠的發(fā)電效益。 在保證整個(gè)防洪安全的前提下，如何合理的對(duì)水電廠水利樞紐工程進(jìn)行控制，滿足電力需求，及時(shí)的獲取和利用水情信息，實(shí)現(xiàn)對(duì)水電廠水情的實(shí)時(shí)調(diào)度，使水電廠水利樞紐發(fā)揮最大的作用，是當(dāng)前所有水電廠閘門(mén)控制系統(tǒng)亟待解決的重要課題之一。水資源作為人類生存不可或缺的條件之一具有豐富的利用價(jià)值。數(shù)據(jù)表明，水電行業(yè)具有豐厚的利潤(rùn)和發(fā)展空間。基于水資源具有清潔可再生的優(yōu)點(diǎn)，其在電力結(jié)構(gòu)調(diào)整中占有重要地位。 因此，科學(xué)管理水資源及進(jìn)行水資源的優(yōu)化調(diào)度成為當(dāng)前關(guān)注的熱點(diǎn)。在這種背景下，閘門(mén)分布式控制系統(tǒng)便應(yīng)運(yùn)而生，在合理輸送、節(jié)制和分配水資源，實(shí)現(xiàn)閘門(mén)系統(tǒng)自動(dòng)化的過(guò)程中起到重要的作用。 本論文以清江隔河巖水電廠的實(shí)際概況和功能需求進(jìn)行調(diào)研和分析，運(yùn)用分布式控制系統(tǒng)的設(shè)計(jì)原理開(kāi)發(fā)了一套集控制、維護(hù)、管理于一體的閘門(mén)分布式控制系統(tǒng)。該系統(tǒng)不僅能對(duì)大壩整個(gè)閘門(mén)系統(tǒng)進(jìn)行集中式管理，分布式控制，還具備自診斷、培訓(xùn)等功能，提高了系統(tǒng)的自動(dòng)化程度。 論文結(jié)合當(dāng)前先進(jìn)的通信和網(wǎng)絡(luò)技術(shù)，貼合清江隔河巖水電廠的需求，對(duì)系統(tǒng)的整體結(jié)構(gòu)進(jìn)行規(guī)劃。在硬件設(shè)計(jì)方面，本文囊括了設(shè)備選型、電氣控制原理圖設(shè)計(jì)、通信網(wǎng)絡(luò)設(shè)計(jì)、傳感器的選擇等方面的內(nèi)容，對(duì)整個(gè)流程進(jìn)行了詳細(xì)設(shè)計(jì)；在軟件設(shè)計(jì)方面，本文對(duì)包括主程序在內(nèi)的通信、觸摸屏、故障報(bào)警、閘門(mén)開(kāi)度與液壓油缸位移量相關(guān)的程序都進(jìn)行了設(shè)計(jì)，并使用WINCC組態(tài)軟件完善上位機(jī)頁(yè)面；在閘門(mén)同步控制方面，本文針對(duì)閘門(mén)開(kāi)度與液壓油缸之間的關(guān)系提出一種新算法，通過(guò)項(xiàng)目實(shí)踐證明了新算法能減少閘門(mén)開(kāi)度測(cè)量誤差，保證閘門(mén)工作的可靠性。
[Abstract]:The gate plays a very important role in the normal operation of hydropower plants. It not only undertakes the tasks of power generation and flood control, especially in the flood season, the effective operation of the gate system is the guarantee of the flood control safety of the whole power plant. At the same time, it also affects the power generation efficiency of the whole power plant. Under the premise of ensuring the whole flood control safety, how to reasonably control the hydro-power project, meet the power demand, obtain and utilize the hydrologic information in time, realize the real-time operation of the hydro-power plant, It is one of the most important problems to be solved urgently in the gate control system of all hydropower plants. As one of the indispensable conditions for human survival, water resources have rich utilization value. Hydropower industry has a rich profit and development space. Because water resources have the advantages of clean and renewable, it plays an important role in the adjustment of electric power structure. Therefore, scientific management of water resources and optimal regulation of water resources have become the focus of attention. In this context, the gate distributed control system emerges as the times require, and in the rational transportation, control and distribution of water resources, The process of automatic gate system plays an important role. Based on the investigation and analysis of the actual situation and functional requirements of Geheyan Hydropower Plant in Qingjiang River, this paper develops a set of centralized control and maintenance based on the design principle of distributed control system. This system can not only manage and control the whole gate system in a centralized way, but also has the functions of self-diagnosis, training and so on, which improves the automation of the system. Combined with the current advanced communication and network technology, the paper plans the overall structure of the system according to the needs of Qingjiang Geheyan Hydropower Plant. In terms of hardware design, this paper includes the selection of equipment, the design of electrical control schematic diagram, Communication network design, sensor selection and other aspects of the content, the entire process has been designed in detail; in software design, this paper includes the main program, including the communication, touch screen, fault alarm, The programs related to hydraulic cylinder displacement and gate opening are designed, and WINCC configuration software is used to perfect the upper computer page. In the aspect of gate synchronous control, this paper proposes a new algorithm for the relationship between gate opening and hydraulic oil cylinder. It is proved by project practice that the new algorithm can reduce the error of gate opening measurement and ensure the reliability of gate operation.
